My situation in these unusual circumstances is that music games meetings were canclled :L, but I had much more time than usual to play with a non-musician adult and a non-musician pre-schooler. Ukulele, glockenspiel and guitar were used.

That was an occasion to seek simplified arrangements to some items from the library. I will add these variants soon. What worked for me so far was:Into the Labyrinth — a version with an additional board for showing current position (played many times actually…),Circle of 5 — a currently tested version,
we also played a modification of Drum Talk by John Scalici (it's shown on YT - basically it's more for teacher-students situation).

There is an app tag, although not very populated. Seems like some computer mediation fits the times.
I just encountered some by the guide of deepfun.org.
As the apps are in Flash it also might be the last moment to engage with them.
Also… if you look for advanced modern music, it's "not that". Themes are rather: ostinato, horizontal organization, a scale…
